To plant fruit trees, 秒兒for example, one of the 現海bottlenecks limiti腦件ng the developme火知nt of fruit producti小厭on is a serious lack of investmen民農t, of which the lac村一k of soil fertility inputs is舞綠 the most promi店的nent aspect. Some fruit farm微數ers say that he has a l話議ot of fertilize黃那r every year to nitrogen, phosp答懂horus and potassium content of suffici亮能ent compound fertilizer, but why is it 司我still difficult to high yield, high qu黑風ality orchards?

In fact, these farmers ar子門e not aware of the importance of effe務就ctive fertility. Putting in more 外聽is not the same as util事低izing more.

Fertility that can b數畫e utilized by fruit trees in that year 村些can only be converted into 街照economic benefits in that yea來務r.

Take, for example, the physiolo藍窗gical diseases of the 照議orchard. Yellow 計房leaf disease occurs in兒風 fruit trees when there is an iron de山北ficiency, and small 森林leaf disease occurs in frui照唱t trees when there is就快 a zinc deficiency. B鐘綠ut yellow leaf disease小什, small leaf disease is n村件ot the whole garden or the whole tre筆音e occurs, often in a la吧體rge branch on a very服船 obvious performance.

Is it possible 地謝that on the sam哥妹e piece of land, only the件志 root system corr信人esponding to the branch w兵說ith the disease鐘冷 is deficient in soil?

In fact, it is the insuffic拍地ient supply of effective fertilizer t一子hat causes the local defi都弟ciency.

To improve the effect通為ive fertility, 東可we must consider the utilization 站作rate of fertilizer. As far as the工光 three major elements are concer少房ned, the current utilizatio你輛n rate is quite low鐘場. The more consistent靜鐘 view is that the utilizat車一ion rate of nitrogen fertilizer is 30% 知做to 35%, phosphorus ferti家麗lizer is 10% to 15%, 歌放and potassium fertilizer is 40% to 45山路%. And in these element老不s there are als多暗o mutual antagonism between the r河拿ole of phosphorus近輛 fertilizer application is too large機讀, will inhibit the absorpt爸舊ion and utilization 理村of nitrogen fertilizer.
